2k2 WGP Autococker questions

I'm assuming I don't need my name or anything to post a picture of my marker, but tell me if I'm wrong. And it has the ANS pump kit, delrin bolt, SP linear barrel and BL Torpedo reg.

Okay so I have a couple questions about my 2k2!
1. Is there any way to make it quieter? Some people at my local field have very quiet autocockers. I am running a 45/45 outputting about 600 psi.

2. I've been wondering about converting it back into the original cocker, I have the pneumatics and everything that came with it stock. What is your opinion on this, which one do you prefer and if I did convert it back what are some things I should know (I'm not experienced with autoclers)

3. Are there any helpful upgrade recommendations, CCM kits, etc.

4. How to stop it from farting (when the rod under the bolt is released when pullin the trigger, it farts, but overall still is fully functional)

Tuning it to have the lowest lpr pressure possible is how I got my autococker so quiet. But you can't do that with a sniper. I think if you found a good spring set up, that would help quiet it down, as well as eliminate the farting. But I'm more of an autococker person, less of a sniper person. I'm sure there are others who would be more helpful. I want to get a sniper though, I love pump, I use a Sterling. But mech cockers are just the absolute most fun guns to use. My suggestion is to have one gun set up as a mech, and one set up as a sniper. (So buy a second one )

As I understand it, the farting sound comes from hammer bounce. You can fix this by sweet spotting your cocker,I will try to find a guide when I get home. This may not completely fix your farting, if this is the case you might try a new spring kit
